WILLIAM JOSLIN, OF CLEVELAND, OHIO.

IMPROVED CLOTHES-WINGING MACHINE.

I Specification forming part of Letters Patent N0. 36,218, dated August 19, 1862.

To all whom it may concern:

Be it known that l', WILLIAM J osLIN, of Cle ve' land, in the county of Cuyahoga and State of Ohio, haveiuvented a new and useful Improvement inClothes-Wrngers; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making part ofthis specification. v

The nature of my invention consists in a simple arrangement oflevers and springs for pressing the rubber rollers together, and in the employment of a double right and left hand circular inclined plane or section of a doublethead screw for holding the machine upon the tu wringing-machine. Fig. 2 is an inside end elevation. Fig. 3 is atop view of the same. Fig. 4 is a view edgewise of one ofthe double circularinclined planes. The red lines represent a face view.

A and A2 in Fig. l are the ends or standards, each having jaws, between which the tub passes when fastened to it, as shown byK and K2 in Fig. 2.

B and B2 are the rubber rollers, between which the clothes Apass in the operation of wringing. i

C and C2 are crooked or somewhat S -shape'd levers, being fastened to the standards by means of pins in the ears d andd2 on Vthe outside of the standards A and A2 and `working parallel with the rollers B and B2.

D and D`2arebars or rods which hold the ends' or standards A and A2 firmly in their position.

E and/ E2 are caps or boxes (shown byred lines) resting upon the tops of the axis of the upper roller, B. Thetops of the caps or boxes upon-which theleversC and O2 restare rounded, so that the levers may work or rise and fall with ease. The bottom of the cap E and the bottom of the cap E2 are made concave, to [it the pins or axis of the upper roller, B, as shown at E2 in Fig.- 2. The caps E and E2 work in 'vertical slots, as shown' at E and E2 in the top springs. The loop-spring F is passed under'- the lever C, toward the cap E, and over the topl The spring F is adjusted to vmake more or less pressure on` Figure l is a front elevation of my improved of lever C in the same manner as the spring F.y

Metallic springs may be applied and adjusted in the same manner as the rubber springs. By moving the springs F and F2 towardthe center of the levers O and C2 the pressure is diminished, so that an'y desired pressure may be produced with very little trouble. By. this arrangement of levers and springs the pressure is nearly the same with a thick or thin article, because the springs move up and down with the levers, and the pressure does not increase as fast as if one end of the springs were fastened to some stationanv part of the machine. The difference of pressure upon a thick or thin article seems to be the dilerence between the spaces moved through bythe notches on the bottom of the levers O and C2 and the notches onthetop ofthelevers C and C2.. If the springs F and F2 are placed in 'the notches indicated by the red lines V and V2, when the notches in the bottom of the levers C and C2move up on the curved lines X and X2 to the points O and O2 the notches on the top of the levers O and O2 will have moved on the curved linesW and W2 to the points S and S2, thereby causing the springs V and V2 to expand one-half less than they would have expanded if the lower -endof the springs were attached to a stationary part of tlie machine. It will now be seen that the expansion or pull of the spring V is up on the lever O and down on the lever C2, and the expansion or pull of the spring V2 is .up onthe lever.C2 and down -on the lever C,

therebyr causing nearly the same pressure on a thick or thin article when passedbetween the rollers B and B2, which is a result in mechanicsV very much desired by spring and lever pressure. I have said the diiferenceof pressure upon a thick or thin article seems to be the difference between the spaces moved through by the notches on the levers. true if the springsdid not pull up ou the levers; but the springs, pulling up on the levers aswell as down, produce nearly an equal pressure, as above stated, the thickest article re ceivng the greatest pressure. -K and K2 in Fig. 2 are the jawswliich hold This would be attached to the levell 23 is a cable 41 which is for the purpose of operating the valve in a manner to be described in detail later.

The links 22 and 25 are supported on the underside of the vehicle by means of brackets 42 so that the same will not jolt up and down while the vehicle is in operation.

The valve 19 is normally held in inoperative position by means of a coil spring 43 one end of which is secured to the vehicle at any desired point, and the other end preferably to the bell crank lever 26 so as to hold the plunger 28 in raised position.

The operation of my device is as follows After the proper connections have been made and the reservoir filled with sand, the device is ready for operation and in case the vehicle is being driven over slippery roads all that is necessary is for the ldriver to depress the plunger 28 and cause the tooth 30 to engage with the underside of the floor board. This movement will force the pivot of the lever 23 backward and allow the lever to pivot in the clamp 44 which is attached to the brake rod 40. This backward movement shifts the valve 19 so that the opening 20 assumes the position indicated by dots in Fig. 4. This movement also tightens up the cable 41 sufficiently so that the valve 33 will be inY position to operate thereby. As soon as pressure is exerted on the brake lever the brake rod 40 and clamp 44 are moved forward while the line 22 moves backward, this brings the opening 20 in alinement with the opening 21 and permits sand or grit from the reservoir to pass into the conduits 17. This movement also pulls the valve 33 into the position indicated by dotted lines in Fig. 1 cutting off the exhaust from the muffler 20 and directing it into the Y 36 through the conduits 17, the venturi 38 and out through the nozzles 39. The exhaust passing through the venturi, speeds up the flow of the gases and forces the grit through the nozzles at high speed. These nozzles are preferably attened at the end so that a wide thin spray of grit issues therefrom. This prevents the sand or grit from being dropped in heaps in front of the rear wheels.

Then it is desired to operate the brakes without causing any discharge from the nozzles, the plunger 28 is moved forward so that the tooth 3() becomes disengaged from the floor board 13. This permits the spring 43 to pull forward on the bell crank lever 26 and place the apparatus in the position indicated in Fig. 3. When in this position it will be noted that the cable 41 is hanging slack so that movement of the lever 23 will not operate the valve 33. The valve 19 is also p-ulled sufficiently far forward so that the opening 21 formed in the sand' reservoir will be over that portion of the valve 19 indicated by dotted lines in Fig. 3, and any rearward movement of the valve 19 will not be sufficient to permit the dropping of any sand, so that the brakes can be manipulated without any exhaust passing through the nozzles or without dropping of any sand.

I'Vhile I have specified sand as being used, it is obvious that the reservoir 15 may be filled with any other kind of relatively fine grit and accomplish all the purposes of my invention.

I may also if desired-eliminate the Y 32 and valve 33 and cause the exhaust to pass through the nozzles at all times without departing from the spirit of my invention. The essential feature being to utilize the eX- haust or some other rapidly flowing body of gaseous medium through a venturi or tube into which grit is discharged so that the grit will pass from the nozzles at a relatively high or accelerated rate of speed.

Having fully described my invention, what I claim is In a sander for motor vehicles a downwardly and rearwardly extending nozzle carried by said vehicle and located in front of and in close proximity to each of the rear wheels thereof, a venturi secured to each of said nozzles, a sand reservoir having an opening in its bottom, an inverted Y secured in said opening, a sliding valve carried by said Y for opening and closing said opening, a conduit secured to the side of each venturi and communicating with said venturi at its point of greatest restriction, the opposite ends of said conduit being secured to the branches of the wire, a conduit secured to the end of each venturi, the opposite ends thereof secured to the exhaust pipe of a motor vehicle, means carried by the exhaust pipe for directing the exhaust into said conduits, a lever having one end connected to the brake rod of said vehicle, a link pivotally `secured to the opposite end of said lever and to the sliding valve, a flexible connection between the last'mentioned end of the lever and the exhaust directing means, a support to which said lever is pivoted intermediate its ends, and means for moving said support whereby the valve operating and exhaust directing means can be placed in operation simultaneously with the brak ing mechanism of the vehicle when desired.

In testimony whereof, I have signed my name to this specification.
